Product description
NuPrime STA-9X, a 2 X 130 W class A+D stereo power amplifier, bridgeable to a 330 W mono amplifier. Designed with an improved harmonic circuit that mimics the most attractive characteristics of tube and class A amplifiers without suffering from their disadvantages and limitations. The frequency response of the STA-9X up to 50 kHz elevates vocals to an emotional experience, and the upper register of instruments mimics the shimmering heights of a live performance.
"The sound is a bit warmer, just like the STA-9, and has significantly better dynamics, resolution, and speed. The 9X delivers 130% more power than its predecessor."

The STA-9X amplifier is an evolution of the ULCAM (Ultra Linear Class A Module) Class D design of the STA-9, incorporating design concepts from AMG-STA. By combining a robust, high-impedance amplifier circuit in the preamplifier stage with a Class D output stage featuring double feedback, the STA-9X delivers a warm and dynamic sound with remarkable speed and clarity. NuPrime enhances the traditional Class D switching design by using a self-oscillating circuit to generate pulse width modulation. The STA-9X switches at a frequency of 750 kHz (the highest on the market), which is far above the CD sampling frequency of 44.1 kHz. Most Class D amplifiers switch at 300 kHz or lower.

"The ensemble is complemented by NuPrime's new linear power supplies with high-efficiency ring core transformers for reduced high-frequency noise and better low-frequency performance. The damping effect of NuPrime's proprietary isolation feet absorbs and interrupts vibrations that degrade sound performance. The overall result is an unmatched transient response and an amazing level of dynamic power."
In summary, the NuPrime STA-9X has a sound profile that is generous, transparent, dynamic, luxuriously structured with exquisite upper registers.


  • "STA-9X Single End Non-Negative Feedback Class A and Dual Feedback Class D amplifier design is improved compared to STA-9 and originates from AMG STA. This design allows STA-9X to produce more details and higher resolution than STA-9."
  • Stereolocation can be bridged to monolocation.
  • Improved circuit for harmonic overtones that creates warmth and natural sound characteristics.
  • Very reliable in unloaded condition and improved short-circuit protection.
  • "130% higher output current than STA-9 means that speakers with low impedance get better dynamics and power."
  • 'It operates at a 750 kHz switching frequency and provides high resolution with extended frequency.'
  • A new linear power supply with a high-efficiency toroidal transformer reduces high-frequency noise and improves low-frequency performance.
  • The signal path avoids cross-connecting capacitors, resulting in a frequency response at DC level for pure musical enjoyment.


NuPrime sound:

  • Wide soundstage
  • "Bred, lightning-fast dynamics"
  • Ultra-low distortion and noise
  • "Music emerges from a pristine background, with a sense of detail and preserved nuances."
  • In summary, NuPrime's sound character clearly differs from - and even surpasses - the soft, pleasant sound that we often associate with most tube amplifiers or the dry, clinically edgy sound that we often associate with solid state and switch technology. It is rare for an amplifier to achieve an ideal balance between richly textured timbres and overtones, authority in the bass register, astonishing dynamics, exquisite low-level details, and a completely apparent, fully dimensional soundstage against a backdrop of miles of silence.
